The g'mara is discussing loans. R. Huna said: if a dying man consecrated all of his property and then said "I owe a maneh to X" he is believed (and X is paid) because no one would conspire against sacred property. (That is, he is not stealing sacred property but, apparently, undoing a small part of the transfer to satisfy the debt.) The rules are different for an inheritance, however; if the man says to his children (who stand to inherit) "I owe a maneh to X" they pay him if and only if he then says "give it to him". (174b)

I'm a little surprised that children have a higher status than the temple in this regard -- children don't have to pay out from the estate unless directed to but the temple does.
